APPARATUS FORTEMPERING CREAM, 800.

SPECIFICATION forming part of Letters Patent N0. 711,009, dated October14, 1902.

Application filed May 9, 1901. Renewed September 12,1902. Serial No-123,121. (No model.)

To all whoa-t it may concern:

Be it known that I, DAVID TOWNSEND SHARPLES, a citizen of the UnitedStates of America, and a resident of VVestchester, in the county ofChester and State of Pennsylvania, have invented certain new and usefulImprovements in Apparatus for Tempering Cream, &c., of which thefollowing is a specification.

My invention relates particularly to the tempering of cream or milk,though applicable to other uses involving the mere agitation of theliquid operated on.

Heretofore the body of liquid to be-tempered has been cooled or heated;as the case may be, by a continuous or intermittent flow of cold or warmwater through pipes fixedly immersed in the vat, and inasmuch as thesefixed pipes would not naturally temper the whole body of stored liquiduniformly they have also been arranged so as to be capable of swingingin the vat, and have been so swung during the passage of the temperingliquid through them by means of a suitable driving mechanism operativelyconnected thereto, thus constantly changing the position of the pipes inthe stored fluid and also keeping the latter sufficiently agitated orstirred to secure an approximately uniform effect upon the whole mass.

The main object of my invention is to se-v cure the advantages referredto in the latter construction while at the same time retaining thesimplicity of the construction first mentioned and providing anautomatic and advantageous method of operation dependent solely upontheinilowing stream ofliquid.

The invention is fully described in connection with the accompanyingdrawings, illustrating a simple mechanism adapted to carry the same intoeffect.

Figure 1 is a partly-sectional elevation showing the movable coil orreceptacle hereinafter referred to in floating position and indicatingin dotted lines the sunken position of the same. Fig. 2 is a sectionalplan view taken on the line 00 a: of Fig. 1. Figs. 3 andi e showslightly-modified forms of mechanism.

A represents a storage vessel or vat of any desired form for the liquidto be cooled or heated or stirred, as the case may be.

B is the floating receptacle for the tempering or passing liquid, whichis preferably made up of coiled pipe to such size and form as to looselyfit within the walls of the vat and freely rise and fall therein and ofsuch displacement as to cause the same to normally float upon the storedliquid, but to sink therein when it is filled to a greater or lessextent by the inflowing liquid. The latter is supplied to the coilthrough a vertical feedpipe. This feed-pipe 0 extends to a greaterheight above the coil B than the depth of the vat and is formed with afunnel-shaped top. c,which is arranged directly belowafixedsupply-nozzle E, through which the inflowing liquid is delivered, so asto receive the latter in all positions of the vertically-movablereceptacle, a fixed guide-bearing F being preferably provided to insurethe maintenance of the funnel-top c in receiving position beneath thenozzle E in all positions of the receptacle with which the pipe 0 risesand falls.

The tempering coil or receptacle B is pref erably provided also with asiphon extension D, the short branch d of which is higher than the depthof the vat, though not so high as the feed-pipe C, so as to permit thecoil to freely sink to the bottom of the vat while the long dischargingbranch freely depends outside of the latter. The discharging capacity ofthe siphon D is greater than the inflow through the feed-pipe O, andsuitable cocks may be provided to regulate the relative inflow throughthe nozzle E and the outflow through the siphon when the latter operatesas will now be described.

\Vhen the empty coil or receptacle B is laid fiat upon the body of creamor other liquid in the vat, it will float thereon until the supply ofinflowing liquid "fed thereto through the nozzle E and feedpipe O hassufficiently increased its weight, when it will sink through the body ofthe liquid to the bottom of the vat. .The continued inflow of liquidwill then fill the coil and rise in the pipe 0 and siphon D until thelatter is caused to operate, when the coil will gradually empty, owingto the discharge capacity of the siphon being greater than the inflowingstream, as previously stated. This emptying of the coil finally causesit to automatically rise again to the surface of the stored liquid to beagain filled and sunken as before, the automatic filling and emptyingand the resulting rising and falling of the coil B being automaticallycontinued so long as the stream of inflowing liquid is continued, withthe obvious effect of stirring or agitating the whole body of storedliquid and uniformly tempering the same as desired.

It will thus be seen that the stirring or agiration of the liquid to betreated, which is required to secure uniformity of action upon the wholebody of liquid, is automatically effected directly and continuously bythe mere passage of the inflowing liquid through the movable receptacletherefor, causing the alternate filling and emptying and correspondingfall or rise of said receptacle, as described.

The particular mechanism shown for carrying out myinvention may ofcourse be readily modified. For instance, in Fig. 3 of the drawings thesiphon is dispensed with and the liquid is withdrawn from the sunken receptacle by means of a suitable Valve V at the bottom of the vat, whichis closed when the coil or receptacle B is floating on the storedliquid, but widely opened when the receptacle has been filled and sunkento the bottom, so as to quickly empty the same, and thus cause it toautomatically rise again. In Fig. 4the inflow is shown to beautomatically cut oil by the sinking of the receptacle B which carries aloose sleeve S, adapted to cover or uncover the discharge-openings fromthe supply-pipe E, so that a smaller siphon d will serve to empty thefilled receptacle and cause it to automatically rise again.

It will be understood that myinvention is adapted not only to efiectautomatically the tempering of a stored body of liquid as primarilyintended, but also to effect automatically the stirring or agitation ofa stored body of liquid without changing its temperature, if so desired,the relative temperature of the passing liquid determining whether ornot the tempering effect is produced.

What I claim is 1. The combination with a liquid-storage vessel of aliquid-receptacle therein arranged to communicate with a supply-nozzleand having a displacement greater than its unloaded weight and less thanits loaded weight, and an automatic emptying mechanism for saidreceptacle whereby the latter is caused to alternately rise and fall inthe stored liquid.

2. An apparatus for tempering or agitating a stored liquid consisting ofa vat, a floating coil or receptacle having a siphon extension and afeed-pipe extension of greater height than said siphon, and asupply-nozzle for said feed-pipe, said coil being free to rise and fallin a body of liquid contained in the vat while maintaining communicationwith said supplynozzle and having a displacement greater than itsunloaded weight.
